The popularity of BMW can be gauged from the number of these cars that one gets to see on the road while driving through Pontiac. However, owning a BMW also comes with its own set of challenges like regular maintenance and service that are essential for its smooth running and better performance. Despite your best efforts issues will still crop up as your BMW gains miles and one such common but serious issue is related to your BMW shutting off while driving. Here in this article, we will discuss the various factors that can cause your BMW to shut off while driving.
Problems with the Battery The battery is a crucial component of your high-end car that is responsible for providing the charge to the spark plugs to kick start the combustion process. Whenever you experience your car shutting off while driving, then it is time to have a look at the battery of your car. Most people opine that the battery doesn’t power the car so it is worthless to check it, however, the battery is responsible for starting your vehicle and when the battery is not able to charge itself and then your vehicle will shut off immediately while driving. The battery of your car is charged by the alternator whenever the car is running and if the battery is dead, then the charge provided by the alternator is futile. Besides that, there are instances where corroded terminals of the battery cause these kinds of problems because they disrupt the flow of charge between the battery and various components.
Crankshaft Position Sensor Failure There are various sensors in your car that keep a tab on the functioning of the important parts of your vehicle. One such sensor is the crankshaft position sensor which keeps a tab on the moving part of the engine and also helps in the process of proper fuel injection and ignition. A faulty camshaft position sensor can be the biggest hindrance to the smooth running of your BMW because it will not be able to send valuable information regarding the position of the piston to the engine control unit resulting in a misfire and often your car shutting off in the middle of the road. In addition to the above problem, you will also observe that the fuel efficiency of your vehicle is reducing gradually and the check engine light on the dashboard of your car is getting illuminated.
Malfunctioning Engine Control Unit The engine control unit (ECU) is like the brain of your car that controls the functioning of the several parts connected to the engine. The ECU collects information from various parts of the engine and keeps a tab on the functioning of the various components so that the engine performs optimally.
However, a malfunctioning ECU can lead to a host of issues like a sudden drop in power, fuel efficiency, and spark loss which can cause your BMW to shut off while driving. Furthermore, you might also experience jerking and stalling of your car while driving. The ECU is a very complex part of your car and diagnosing it is not at all easy. This is why you must take your BMW to a certified repair shop for getting it inspected.
Bad Fuel Pump If you observe that your high-end vehicle is turning off while driving and then turning back on imminently, then this is caused due to a blocked fuel pump in your car. The engine always requires a proper supply of pressurized fuel for efficient combustion and this fuel is provided by the fuel pump to the combustion chamber. However, if there is any sort of issue with the delivery of fuel to the engine, then it is going to shut off. Most of the time you have to replace the bad fuel pump and along with it, the BMW specialist would also have a look at the fuel filter of your car to make sure that it is not clogged which can create problems.
Finally The above-discussed factors are some of the leading causes behind your BMW shutting off while driving. Most of the time drivers choose to ignore the problem during its initial stage which complicates it subsequently. Whenever you face this issue and then make sure to visit a reputed BMW auto repair shop immediately.
